@ravinp58 I dont believe this is a Spanish mackerel. They are much smaller in size and have big anatomical difference compared to King mackerel
The King Mackerel has a similar body to other members of the family, and is often confused for the smaller Spanish Mackerel by anglers. Young King Mackerel will exhibit light yellow spots, approximately 1 cm in diameter, on their sides. This is very similar to the Spanish Mackerel, which keeps its spots throughout its life, and what leads to most of the confusion. King Mackerel are silver to gray in color with purple and green iridescence on live fish immediately after being pulled from the water. They also have a distinct lateral line which is a sense organ used to detect movement in the surrounding water. Lateral lines are usually visible as faint lines running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. The receptors in the line, known as neuromasts, each consist of a group of hair cells, whose hairs are surrounded by a protruding jelly-like cupula, typically 1/10 to 1/5 mm long running the length of their body. This line makes a sharp drop from the dorsal and is the side in which the backbone is located. This is usually the top of an animal, although in humans it refers to the back. In fishes, it refers to the top, front fin (see Dorsal fin). It is the anatomical opposite of ventral (referring to the front or underside of an animal). side toward the ventral side of the fish, approximately 3/5 of the way down the fish. This drop in the lateral line is considered to be distinctive and characteristic of the King Mackerel, and can be used to distinguish it from other similar mackerel species.
King Mackerels are common up to 1 meter and 15 kg, but have been reported up to 184 cm in length and 45 kg weight.
